Abstract
Abstract A dispenser for an aqueous sialogogue for the mouth comprises: a) a reservoir for the aqueous sialogogue solution; b) passage means leading from the reservoir to a spray head; and c) a plurality of orifices in the spray head, whereby actuating the spray head causes a plurality of streams to be directed to those regions of the mouth most dry in a reniform pattern. Preferably a metered amount of sialogogue is delivered by an actuating means selected from the group consisting of a hand-activating spray pump, a bulb-activated spray pump or an aerosol propellant. The sialogogue solution comprises: a) from about 2 to about 3 wgt % of food-grade organic acidulant; b) a food-grade sweetener benign to stomic microflora; and c) a saturated calcium phosphate solution, whereby the production of human saliva is promoted in situ without corrosion, infection, or dissolution of human teeth.
